I've only tried it with xvid, but if the -bf flag is set during encoding, the output video appears corrupted when playing in VLC... totem plays them fine. I assume that means the problem is due to VLC's use of ffmpeg in decoding. I can provide a sample file if necessary. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/28#comment:2> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
